The amount that you need to invest will depend on the visa route that you choose. The Innovator visa requires a minimum investment of £50,000 whereas the investor visa requires either £2m, £5m or £10m depending on the speed at which ILR is required. The Tier 2 work visa does not require investment but you are able to own up to 10% equity in the business you work for which can range anywhere from £25,000 upwards.
